Android app development starts with a clear product goal and an awareness of device diversity. Defining the MVP, selecting an architecture, and outlining core user flows early helps keep the initial release focused and reduces rework as the app grows.

Once the foundation is in place, attention turns to UI consistency, performance, and compatibility across OS versions and screen sizes. Solid state handling, careful networking, and reliable analytics/crash reporting make the app easier to support and iterate on after it reaches Google Play.
